NVD Description

Note: Versions mentioned in the description apply only to the upstream imagemagick package and not the imagemagick package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

There are 4 places in HistogramCompare() in MagickCore/histogram.c where an integer overflow is possible during simple math calculations. This occurs in the rgb values and count value for a color. The patch uses casts to ssize_t type for these calculations, instead of int. This flaw could impact application reliability in the event that ImageMagick processes a crafted input file. This flaw affects ImageMagick versions prior to 7.0.9-0.
